bsursolides, or bissursolides, that is, Second sursolides. seconde sursolides, or double sursolides. But I maie call them seconde squares of cubes, alludyng at the same name. Howbeit if I looke to their forme and nature, I shall be inforced to call thē, longe cubes of cubes, or longe cubike cubes.
Squares of
squared squres.
And so by like reason, doe I cal the nexte nombers square cubes of cubes, or square cubike cubes: whiche other men doe cal zenzizenzizenzikes, that is squares of squared squares.

But other men for aide of woorke, in extraction of rootes, haue giuen theim soche names, as maie beste put menne in remembraunce of redy worke therein.
